In my previous blogs, the focus has been on highlighting the value that Dell vSAN Ready Nodes incorporate in a standardized market segment. These value additions include the variety of form factors available, the existence of 13 models with Identity modules, and the special benefits that the integration with Open Manage Enterprise provides.
But, what about the workloads? One key factor to decide for an infrastructure choice is the benefits and advantages it may have for the type of workloads the business requires. Today, the ability to run effectively and incorporate enterprise features such as protection or replication determine the choice of platform that customers make.
In a world where cloud native applications (CNA) are the natural choice for new deployments, it is relevant to describe how Dell vSAN Ready Nodes behave is such scenarios.
Speaking about paradigms, CNA is to application development like unstructured data is to storage. The relevance of object storage, and the growth that it experiments every year, is substantial.
Wouldn’t it be great to put all these together under the Dell vSAN Ready Node hood?
There is a great VMware platform to simplify your DevOps experience by adding Kubernetes to your infrastructure, making it ready to run modern applications and minimize operational complexity. VMware Tanzu provides a self-service, consistent Kubernetes experience for developers to maximize their productivity, and security and data protection policies and features, out-of-the-box.
vSphere with Tanzu supervisor cluster architecture
A cluster that is enabled for vSphere with Tanzu is called a Supervisor Cluster. It runs on top of an SDDC layer that consists of ESXi for compute, NSX-T Data Center or vSphere networking, and vSAN, like in a Dell vSAN Ready Node. vSAN shared storage is used for persistent volumes for vSphere Pods, VMs running inside the Supervisor Cluster, and pods in a Tanzu Kubernetes cluster.
Dell ObjectScale, based on the Dell ECS platform, delivers a new, software-defined, microservices-based architecture using Kubernetes to provide enterprise-class object storage for modern, cloud-native applications in VMware environments.
Dell ObjectScale deployment option for VMware environments (Dell vSAN Ready Nodes)
Dell ObjectScale integration with VMware vSphere with Tanzu and the vSAN Data Persistence platform enable supporting cloud-native applications on Dell vSAN Ready Nodes. It also enables a global management platform for the distributed storage infrastructure under a single namespace with universal content access.
The components for the solution are:
- VMware Cloud Foundation with Tanzu
- NSX-T
- vSAN (in this example, Dell PowerEdge R650 vSAN Ready Nodes)
- vSAN Data Persistence platform
The solution is built upon four Dell PowerEdge R650 vSAN Ready Nodes configured in a vSAN cluster. This includes three VMware NSX-T manager nodes and three edge nodes for redundancy and high-availability. VMware NSX-T manager nodes were installed on the same vSAN cluster to conserve resources in a lab environment. In a production environment, NSX-T manager nodes can also be installed on an external cluster to provide management and data-plane separation and availability.
This architecture integrates Dell ObjectScale with VMware vSphere with Tanzu through vSAN Data Persistence platform enabling customers to deploy software-defined object storage (stateful services). It also makes containers as easy to manage as VMs. IT departments can deploy cloud-native web and mobile applications, dev/test environments, and AI/ML and analytics platforms over the same infrastructure that host their legacy VMs.
There are different deployment options available:
- Fully sharing the vSAN Ready Nodes clusters between ObjectScale data services and the workloads to be run
- Creating separate clusters in the vSAN Ready Node farm for ObjectScale data service and the workloads to be run
If you want to learn more about how Dell vSAN Ready Nodes can be built to host cloud-native workloads, see the VMware white paper Dell ObjectScale on VMware vSphere with Tanzu.

Today, most technology companies in the IT space work to offer customers not only the best technology innovations but also those that help simplify their day-to-day lives.
One example of this is the new vCenter plug-in for NSX-T, introduced with vSphere 7.0 Update 3c and NSX-T 3.2. Through this new deployment method for NSX-T, management and operations users can now use NSX-T as a plug-in for vCenter, similar to how earlier versions of NSX were configured. Through wizard-assisted operations, security policies can easily be configured, deployed, and operated within vCenter.
Figure 1. The new vCenter plug-in for NSX-T simplifies security deployment and operations
For Dell HCI platforms such as VxRail, vSAN Ready Nodes, and PowerEdge servers hosting vSAN-based workloads, NSX becomes an optimal network and security engine.
Figure 2. Dell HCI platforms such as VxRail or vSAN Ready Nodes become the perfect targets for the new vCenter plug-in
The whole process is simple. It can be completed by following these steps:
- Install NSX-T Manager and provide a license key.
- Install the new method to configure and operate NSX security, the vCenter plugin for NSX.
- Configure the distributed firewall policies for the HCI cluster:
a. Define infrastructure services as needed (DNS, DHCP, custom…).
b. Create the environment to consume the defined infrastructure services. - Define how the elements in the environment can communicate with each other.
- Define communication strategies for applications in the environment.
- Review and verify the defined security policies before they are published and effective.

The Benefits of Composable Infrastructure for VMware Cloud Foundation on vSAN Ready Nodes
Thu, 25 Aug 2022 17:14:52 -0000

Discussions comparing the public cloud to on-premise architectures have shifted to discussions about the best way to build a hybrid model.
Multi-cloud delivery services alongside on-premise infrastructure seems to provide the versatility that organizations need for business critical missions, however they are often complex and costly. Ending up with multiple administrative teams, toolkits, and processes doesn’t appeal to most organizations as a winning horse.
As usual, simplicity comes to our rescue. An integrated offering that provides customers with the advantages of both the public cloud and an on-premise infrastructure helps organizations with the following:
- Control infrastructure price and performance
- Improve their deployment times and thus time to value
- Minimize cost and complexity, through a single set of skills and tools
Most organizations that are interested in these benefits are not prepared to build a hybrid cloud themselves. Running an on-premise datacenter or building assets in the main public cloud tends to be more familiar for most IT teams, but managing both at the same time may be beyond the capabilities of some existing IT teams.
In these cases, a trusted partner that brings guidance and innovation to follow this path is crucial. Such a partner can provide a set of familiar management tools with all the administrative and analytics capabilities required to monitor business workloads—such as tools that can be extended to multiple public cloud providers, giving organizations the advantages of compelling cost, efficiency, and speed.
Because most organizations today are using virtualized on-premise infrastructure, VMware comes to my mind as a perfect partner for this journey, having a mature technology offering to help companies build a hybrid cloud.
VMware on Dell offers infrastructure to build a foundational hybrid cloud. This architecture makes the on-premise more cloudy and enables workload mobility to place every workload, whether it is in a public cloud or in our on-premise infrastructure.
Dell PowerEdge MX offers a software defined data center that empowers organizations towards a hybrid cloud model. For example, when this infrastructure is coupled with VMware Cloud Foundation (VCF) and VMware on AWS organizations can build a hybrid cloud using popular VMware tools and capabilities.
Figure 1: MX composable infrastructure chassis
MX chassis is built with capabilities that perfectly match vSAN requirements. Each node can hold six drives, which ensures that that two of the drives are caching devices within the vSAN cluster for optimal performance.
A low latency smart fabric is built into the MX design. This minimizes the risk that lack of throughput or excessive latency presents for a hybrid cloud deployment. Expandable and extensible by design, the MX family can deliver cloud value across many technology generations.
Dell MX management is integrated with VMware Cloud Foundation 4.x. The MX hardware has the systems’ management and APIs to hook into the VMware consoles that customers are used to. This way we can deploy VCF into the MX infrastructure though a simplified path that eliminates tedious stepwise processes around setup, monitoring, provisioning, and management.
Dell and VMware have also worked together to improve telemetry and insight, giving operators an improved view of resource utilization for each node and chassis in the MX infrastructure.
In summary, the advantages of running VCF on Dell vSAN Ready Nodes based on PowerEdge MX servers include:
- A scalable network design that provides a low latency, automated and not oversubscribed fabric to support any workload deployment the business may need
- A secured stack all the way from the hardware to the VMware management console
- An integrated management with tool set that helps IT admins provision, monitor, and maintain their MX based vSAN Ready Node farm. One console can manage multiple chassis and even other server and storage types.
Figure 2: MX integrated management simplifies hybrid cloud operations
One way to see the integration of VCF with MX based vSAN Ready Nodes in action is to deploy a new workload cluster of Dell vSAN Ready Nodes MX750c into an existing VCF infrastructure.
Principled Technologies performed this test and showed how simple and straightforward the expansion process is with MX servers. They also showed, by following the same expansion process with two generations of MX servers (MX740c and 750c), that the tools and processes remain the same across server generations.
The engineers completed the expansion process in just two hours and 21 minutes. It took the same time for each of the two server generations.
For more information about this test case, see the Principled Technologies report.
Conclusion
Although building a functioning hybrid cloud to support real business workloads may look complex, it can be simplified if by using the proper technologies and tools. VCF combined with Dell vSAN Ready Nodes MX composable infrastructure offers a perfect duo to reach an organization’s hybrid cloud goals.
